ω-Aryl-9-deoxy-9-methylene-PGF-type compounds

ABSTRACT

This invention comprises certain analogs PGE or 11-deoxy-PGE compounds in which the carbonyl at C-9 is replaced by methylene. Also provided in this invention, are novel chemical processes and novel chemical intermediates useful in the preparation of the above prostaglandin analogs. These prostaglandin analogs exhibit prostaglandin-like activity, and are accordingly useful for the same pharmacological purposes as the prostaglandins. Among these purposes are blood pressure lowering, labor induction at term, reproductive-cycle regulation, gastric antisecretory action, and the like.
